VENDING-MACHINE.

1,397,604. i Specification of To all whom it may concern Be it known that I, ALBERT E. PFAU, a citizen of the United States, residing at Rockford, in the county ofWinnebago and State of Illinois, have invented certain new and useful Improvements in 'Vending-Machines, of which the following is a specification.

This invention relates to vending machines, and more particularly to liquid spraying machines,

The object of the invention is to provide a simply constructed: and eflicient machine of this character whereby the insertion of a' coin or check willjrel'ease the actuating mechanism therefor.

Another object isto provide simple and eflicient means to prevent the actuation of the discharge or ejecting mechanism until released by the coin.

Another object is to provide'novelmeans for ejecting and spraying a liquid from the apparatus. .7 v

Anotherjobject is to provide improved means for ejecting the coin after it has actuated the mechanism. V i

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combi nation and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe invention herein disclosefd .may be made within the scope of what is claimed without departing from the spirit of the invention. y

In the accompanying drawings 2- Figure 1 represents a side elevation partly in section of the apparatus constituting this invention, the casing in which it is inclosed being'shown in section, T

Fig. 2 is a horizontal section through the casing with the mechanism shown in plan view Fig. 3 is a transverse vertical section taken on the line 33 of Fig. 1, I

Fig. 4 is a detail fragmentarylongltudinal section taken on the line'4-4of Fig. '2, and I Fig." 5 is a detail fragmentary transverse sectional view thereof. l

' In the embodiment illustrated, the apparatus constituting this invention is inclosed within a casing 1 divided by a vertical part/1 Letters Patent.

tion 2 into two compartments 3 and 4. Securedto the bottom ofthe compartmentfl is a cup-shaped member 5 having a flange 5, extending therefrom fandseoured to said bottom. This cup-shaped member 5. is de& signed to retain and support a vessel 6 in the form of a bottle which may contain perfume or any other liquid to be vended. A pipe 7 extends into vided at its upper end witha nozzle 8 which projects laterally from the front wall of the casing 1, said front wall 3 being composed of glass or other taransparent material so that the label contained onthe' bottle-may be readily seen from outside the casing so that'the purchaser may know just what kind of perfume he is going toobtain. j j

A tube or pipe 9 leads from'j the nozzle stopper of the bottle andhas a bulb 10 at its rear end, the pipe extendingthroughthe vertical partition 2 sothat thepipe is poSitioned in compartment i near the top there of (see' Fig. 1). This bulb 10 is covered by. a hood 11 against which the upper portion of the bulb is designed to bear, the inner face of the, hood being made to conform to the shape of the bulb as is shown clearly in *ig.1. p This hood 11 is supported by uprights 12 rising from the horizontal partition 13 spaced from the bottom of'the compartment NroFF c emi ted Nov. 22,1921.

said bottle and is pro 4; a'ndwhich is designed to support the mech anism which actuates theapparatus as will;

, be hereinafter more fully described. Belowf this partition 13 is arranged a coin receiving drawer 50, and mounted on the partition are the uprights 12 above described. These uprights 12 arev slotted longitudinally at their upper ends as shown at. 15 and a rod 16 is designed to reciprocate in. the slots. Blocks 17 are carried by this rod and operate asguides, being shapedtojfit within the slots 15. j 1

Carried by the rod 16 isa convex block 18 positioned below the bulb 10 and which is designed to be forcibly engaged with the bulb when the block is raised 'forthe pur.-. pose presently to be. described. .Bars 19 are connected at one end with the rod 16 on" opposite sides of the block 18 and. at their v other end are connected with crank arms 20' which project laterally from shaft 21.

'a rotatable shaft carrying mechanism to operate the compressing means, gear wheels carried by said shaft, and spring retained rack bars in mesh with said gear wheels and operable by movement of said shaft to tension the springs of the rack bars whereby the latter are automatically retracted when the shaft is released.

2. In a machine of the class described, an inclosing casing, a liquid container therein having a nozzle with a bulb connected therewith, reciprocatory means for compressing said bulb to eject the liquid from said container, a rotary shaft, crank arms connecting said shaft with said reciprocatory means, a gear fixed to said shaft, a reciprocatory rack meshing with said gear, cooperating means carried by said rack and casing for locking the shaft against turning, and coin controlled means for releasing said locking means.

3. In a machine of the class described, an inclosing casing, a liquid container therein having a nozzle with abulb connected therewith, reciprocatory means for compressing said bulb to eject the liquid from said container, a rotary shaft, crank arms connecting said shaft with said reciprocatory means, a gear fixed to said shaft, a reciprocatory rack meshing with said gear, cooperating means carried by said rack and casing for locking the shaft against turning, means for releasing said locking means, and means for re moving said releasing means after the compression of the bulb.

4:. In a machine of the class described, an inclosing casing, a liquid container therein having a nozzle with a bulb connected therewith, reciprocatory means for compressing said bulb to eject the liquid from said container, a rotary shaft, crank arms connecting said shaft with said reciprocatory means,

and coin controlled means for releasing said locking means.

6. In a machine of the class described, an inclosing casing, a liquid container therein having a nozzle with a bulb connected therewith, reciprocatory means for compressing said bulb to eject the liquid from said container, a rotary shaft, crank arms connecting said shaft with said reciprocatory means, a gear fixed to said shaft, a reciprocatory rack meshing with said gear, a ratchet bar carried by said rack, a pawl carried by said casing in the path of said ratchet bar for locking the gear against turning, and liftable means connected with said pawl.
